T8 Fluorescent Instant Start Ballasts - High Ballast Factor

Narrow down your ballast search further by choosing how many lamps your high ballast factor (HBF) ballast runs - 1, 2, 3 or 4 lamps. High Ballast Factor ballasts have a power of 1.15 - meaning a 32W fluorescent T8 on an HBF ballast is actually running at ~37 watts.
